Wickr

Free
This chat app lets you send self-destructing encrypted media and messages over a secure system, proving that you don't have to sacrifice usability for the sake of security. You can send basic text messages, images that you can mark up in the app, and 30-second audio recordings as well. Wickr lets you decide when your messages self-destruct on the recipient's device. The app even has a Shredder features that obliterates every trace of your old messages, for when you want to be super secure.
